Looking for a circuit and calculation details for different IF filters for use with CW in my tcvr that operates with an IF of 60MHz.

Hopefully looking to homebrew a 600Hz, 500Hz and/or 300Hz filters to use with my rig. It's also SSB so got to be switchable in and out.

It's for a an SGC-2020 incidentally.

Can anyone advise?

I've seen a link shownming COHN filters but got no idea how the Y, L, C or R values are calculated.... or the pass details.
